EXTENSION PACKIMG CAEE.

Application filed May 1; 1925.

invention while not limited to use in conneci tion with my prior application, `'is nevertheless well adapted for use in connection with a structure such as that shown in my application for Letters Patent of the United States Serial No. ?27,477, filed July 22nd, 1924.

In packing cases such as disclosed in my prior application, I find that it is a Very simple matter to extend such packing cases in any direction, preterably in depth, without changing the essential characteristics of the packing case, that is to say, l can preserve the general shape, the inclined corners, the tastening tlanges which lie within the planes of the adjacent sidcs and are arranged to strengthen the structure without inconvenience, and in fact all the advantages specified in the specification of my prior application, Packing cases ot this type are re-usable, and it sometimes happens that it is very desirable to make the packing case larger because of some other use :tor it, and my invcntion is intended to meet this requirement and to provide a simple andinexpensive structure which Will enable such eX- tension to be readily made. This will be better understood from the description which follows.

Reference is to be had to the accompanying drawings -torming a part of this specification, in which similar reference characters indicate correspondng parts in all the views.

Figure l is a side elevation of my improved packing case.

Figure 2 is a cross section thereoi on the line 2-2 of Figure l.

Figure 3 is a side elevation of a slightly ::nodilied ;term of the invention, and

Figure 4: is a cross section on the line 'ir- 4: of Figure 1.

The body of the packing case can be of any usual type having the sides and ends provided with outwardly extending tlanges top and bottom and at the vertical cornei-s, but I have shown the invention in connection with a structure like that in my prior application referred to, because it is so easy to apply it to this type. As illustrated the main or lower part of the case is practically like that shown in my prior application,

Serial No. %7,163.

.having opposed sides lO 'with inclined parte v;

ll at top and bottom, and outwardly extendng tlanges 12 which corrcspond to :tlanges 13 on the bottom lt. The euds 15 are like those in my other application, and are simlar to the sdes just described. As illustrated in Figures l and 2 I use a type of ea:- tenson comprising side and end portions 16 and 17 which can be corrugated like the other parts to give the necessary strength, and which can be united at the vertical cornere by tlanges 16 or in any suitable way, and these side and end pieces have at the bottom upturned :tlanges 18 which are adapted to seat :thrmly on the tlanges 12 of the lower case section, while the top edges ot sahi parte have outwardly and upwardly extend- .ng ilanges 11.) preferably parallel with the tlanges 18 and adapted to receive the corresponding flanges 20 on the inclined part 21 of the cover 22.

It will he observed that it the extension :LG-17 were not used, the cover 22 would fit on the lower part oi? the case precisely as shown in my 'tormer application, but by adding the extension, the cover applics to the top of this part and the case is therefore considerably deeper. lt will be seen that I preserve the oharaeteristics oi? the original. case, that is that the sides and ends may be corrugated for strength, may have the inclinecl part s and the c-,onnecting tlang'es, and it will be noted thatthe l'langcs 18 and l9 lie within the plane of the wider part oi? the lower portion ot the case so that no less of space in shipping occurs. Also it will be seen by reference to Figure 2 that I can preserve the arrangemcnt reiferrcd to in my prioi: case ol? having the meeting ilanges 12 and l spaced in .such a way as to permit a hoolt to be easily placed under them. llirthermore it will be noted that the extension li3-l7 may be of any desired height, and. that a plurality oi': extensions could be `as easily used, and it will also be noticed that while I have shown and extension to the top, that as the sidcs, ende, and bottoms ot the main part of the casing all have the outwardly e1ttending ilanges, the extension ili-li' might as well be put on the sides or ends as on the top, but the latter would be the usual way ot applying the extension. It will thue be seen that by having one or more extensions, the packing case may be very easily and economically adapted tocontain more or less material as desired. e

In Figures 3 and 4 I have shown a slightly different type of extension in which the extension part is formed of the side pieces 22 and end -pieces23 precisely like those of the lower 'part of thecase, and like the structure described in my prior application. As illustrated in these figures, the side pieces have inelined parts 24 and outwardly extending flanges 25- at the bottom, and the end pieces have correspondng parts 26 and 27, and .these flanges 25 and 27 meet the corresponding flanges in the lower 'part of the i case as-shown in Figure 4. The meeting flanges of the upper and lower parts are coveredby angles 28 as shown clearly in Figures 3 and 4, and bolts may be extended through the angles and through the adjacent flangs to make the joint exceedingly tight and strong. Furthermore 'it will be seen by reference to Figure 4 that the whole oint lies within the plane of the adjaeent sides so as not to interfere with close paeking.

The top portion of the extension 22-23* has the inclined parts 29 and fianges 30, the

lattermeeting the flanges 31 on the inclined part 32 of the cover 33, and the flanges and 31 can be bolted or otherwise fastened together, a As in the other modification, it will be f seen that if the extension 22-23 is not used,

the cover 33 will' fit on the lower'part of the case, and as already stated with reference to the 'structure shown in Figure 2,'the case can be provided with a plurality of such extensions if desired', without at all chang 'ing its characteristics.

I claim r p j 1; An extens on paekng ease comprsng a main member having nclned perpheral i flanges lying within the plane of the adjacent sides of "the case, an extension having inclinedeorners and peripheral'flanges to fitthe flanges of 'the main part of the'case, and a cover having fianges to fit those of the extension and the main part of the case whereby the cover can be used either for the main casegorfor the extension.

:2. An extension packing case comprising amain member having inclined parts and outwardlyextending inelined flangesat the periphery,-an extension having corresponding inclined parts and flanges, and'anang'le V brace uniting the' -flanges of' the main part and the extension.

3. An extension packing case eomprising a main member having inclined parts near the periphery with outwardly extending flanges thereon, said fianges lying within the plane of the adjacent sides of said member, an extension having fianges corresponding to those of the main member and adapted to meet said flanges edge to edge, and an angle brace uniting the said fianges, said brace lying within the plane of the adjacent sides of the case.

4. .An extension packing case comprising a main member having sides and end portions With inelined edge parts and outwirdly extending fianges thereon, an extension having similar sides, ends, inclined parts and flanges, whereby the flanges of the extension and main member meet edge to edge, and' a fastening brace to secure the flanges of said parts together.

5. An extension packing case comprising a main member having sides and ends with inelined edge portions and ontwardly extending flanges, whereby the fianges are brought within the planes of adjaeent sides of the said member, an extension similar to the main member and having similar .inclined parts and fianges, the flanges of the extension being arranged to meet those of the main member, means for fastening the flanges together, and a top shaped to fit either the main member or the extension.

6. In an extensible packing case, :i body having marginal inset portions at opposite sides thereof, and an extension having marginal inset portions eoinciding with the marginal inset portions of the body for fitting contact therewith, said portions being -correspondingly inclined relative to each ROBERT W.
